Customized birthweight standards for a Spanish population

Sequence of changes in myocardial performance index in relation to aortic isthmus and ductus venosus Doppler in fetuses with early‐onset intrauterine growth restriction

“…During the study period a total of 430 scans were performed on 115 IUGR fetuses (median 3, range [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. The proportion of cases with two, three or more than three examinations was 43.5, 34.8 and 21.7%, respectively.…”

“…Only cases with two or more Doppler assessments from diagnosis to delivery were included. Exclusion criteria were: congenital malformations and chromosomal abnormalities, and confirmed birth weight above the 10 th percentile according to local standards 20 . The protocol was approved by the hospital ethics committee and written consent was obtained for the study from all women (IRB 2009/4712).…”

“…Between December 2005 and December 2009, a prospective cohort was created of consecutive cases of singleton fetuses with estimated fetal weight below the 10 th percentile according to local standards 20 with an abnormal umbilical artery (UA) pulsatility index (PI) (above the 95 th percentile) 21 . All fetuses were delivered before 34 weeks' gestation (corrected by first-trimester ultrasonography) 22 in the Maternal-Fetal Medicine Department at Hospital Clinic, Barcelona, Spain.…”

Birth-Weight Differences of Roma and Non-Roma Neonates - Public Health Implications from a Population-Based Study in Hungary

“…For example, the first study about maternal education and adverse birth outcomes among immigrant women to the US from Southern and Eastern Europe after the decline of communist systems did not identify Roma ethnicity while analysing immigrants out of Russia, Ukraine, Poland, and the former Yugoslav Republics (18). The western European study about Spain, with a considerable Roma population, and East Asia, Morocco, and South America did not include Roma ethnicity as a covariate (19). In this regard, our study makes a unique contribution to the literature on birth weight differences between Roma and non-Roma neonates.…”

“…This study indicated that there might be a genetic element in the lower birth weight, but the disadvantage might stem largely from a low socioeconomic status of the Roma population, which was not measured. The recent studies (18,19) about birth outcomes of the European populations do not offer disaggregated Roma data for comparison. For example, the first study about maternal education and adverse birth outcomes among immigrant women to the US from Southern and Eastern Europe after the decline of communist systems did not identify Roma ethnicity while analysing immigrants out of Russia, Ukraine, Poland, and the former Yugoslav Republics (18).…”
